HAND-STAMP.

T0 @ZZ trimm it may concern:

Be it known that I, Louis K. Scorronn, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of @ook and State ofIllinois, have invented certain new and useful Improvements inHand-Stamps, of which the following is :t specification.

This invention relates to improvements in that class of hand stampsshown in my Patent No. 668,021 of February 12, 1901.

The object of the invention is to provide a stamp of the character shownin said patent which will be capable of ready ad- `iustment and whichwill have other advantages hereinafter described.

lrThe invention` in its preferable embodiment, consists in theconstruction hereinafter more particularly described and illustrated andthen definitely claimed.

In the drawings accompanying and forming part hereof: Figure 1 is a sideelevation of a stamp made in accordance with my invention. Fig. 2 is asectional view through the line 2 2 of Fig. l. Fig. 3 is a perspectiveview of the base plate and die plate, the die plate being thrown open.Fig. 4 is a perspective view of two details. Fig. .5 is a sectionaldetail.

Referring now to the details of the drawings by numerals t-1 designatesthe main frame of what is known as the tumbler form of stamp, and asusual comprises a handle 2 for depressing the yoke 3, the ends of thelatter having a spindle 4 connecting them and passing through the sidemembers 5 and 6 of the frame 1D this spindle being the center on whichthe printingcharacters S are tumbled when the handle 2 is depressed inorder to move the printing characters from the inking to the printingposition.

The main base plate is made similar to the base plate of my aforesaidPatent No. 668,021 and also on the same order as the base plate of myapplication Ser. No. 686,930, filed March 28, 1912, and has side arms 12and 14 projecting therefrom, these arms being perforated as indicated at15 through which the aforesaid spindle 4 passes. At the points where thespindle passes through the perforations 15 of the side arms 12 and 14, Iinsert a bushing 1S having a flange 20. These bushings surround thespindle 4 and the ianges 2O are lo- Specifcation of Letters Patent.

cated between the side arms 12 and 14 of the movable base plate 10 andthe side members 5 and 6 of the frame 1. The purpose of these flangedbushings is to prevent contact of the side arms 12 and 14 with the sidemembers 5 and 6 of the frame 1 so that should any ink from the pad oozedown on the side arms 12 and 14, it cannot come in Contact with the sidemembers 5 and G.

The main base plate 10 is provided with the usual flanges 22 and 24 andwithin these flanges is pivoted the supplemental die plate 26, thelatter being hinged on the pivot 23. In order to lock this supplementaldie plate 26 to the main plate 10 and to cause it to spring open whenreleased I provide the following parts-the supplemental die plate 26 isprovided with a grooved pointed pin 30 which7 when the die plate 26 isclosed against the main base plate 10, passes through a perforation 32.On the under side of the main base plate, I provide a sliding catch 34which has an opening 36 throughV which the pointed pin 30 enters whenthe supplemental plate 26 is closed against the main base plate 10.Co-acting with this sliding catch 34 is a spring 3S which is firmlysecured to the under side of the main base plate by means of two rivetsas shown in Fig. 2. A spring finger 42 is provided which may be integralwith said spring 38 and which co-acts with a flange 44 on the slide 34to cause the slide 34 to co-act with the groove in the pointed pin 30and lock the supplemental die plate 26 to the main base plate 10. IVhenit is desired to release the die plate from the base plate the operatormerely has to press upon the flange 46 of the slide 34, moving saidslide 34 against the tension of t-he spring linger 42, when the slidewill be moved so that the pointed pin 30 will be released from saidslide 34, The supplemental die plate may now be opened upon its pivot28.

In order to open the die plate automatically, I provide a spring 50which passes through the opening 11 in the base plate 10 and contactswith the under side of the supplemental die plate 26. This spring, inthe embodiment shown, projects from the aforesaid spring 38. Thus whenthe supplemental die plate 2G is closed against the mainbase plate 10,the former strikes against the spring 50 and shoves it downward untilthe supplemental die plate 26 is closed against the main base plate l0,at which time the spring finger 42 causes the sliding plate 34 to movewithin the groove of the pointed pin 30 and lock the supplemental dieplate 26 to the main base plate 10. W'hen it is desiredl that the dieplate 26 shall move away from the main base plate l for the purpose ofchanging the position of the type 8, all the operator has to do is toshove the projection 46 on the slide 34. This, as before explained,moves the slide 34 against the tension of the spring finger 42 so thatthe grooved pointed pin 30 is released from the slide 34, whereupon thespring 50 forces the die plate 26 outward on its pivots to the po- Isition shown in F ig. 3.

From the foregoing and accompanying drawings it will be seen that I haveprovided a stamp of such a construction that the supplemental die platemay be opened very easily for the purpose of adjusting the type and thatI have also provided a stamp wherein the side arms of the movable dieplate are held away from the side members of the main frame so that theinl: from one cannot be transferred to the other.

Vhat I claim as my invention is:

1. In a hand stamp, a main plate, a supplemental die plate hingedthereto, a sliding latch constructed and arranged to hold said t dieplate to said main plate, a spring secured to said main plate andprojecting through an opening therein against the die plate to force thesame away from said base plate, and a spring co-acting with said slidinglatch to hold the latch in its locking position.

2. In a hand stamp, a main plate, a supplemental die plate hingedthereto, a sliding latch secured to one of said plates and constructedand arranged to hold said plates together, a spring secured to said mainplate and having a member projecting through an opening therein againstthe die plate to force the same away from said base plate, and a springmember co-acting with said sliding latch to hold the latch in itslocking position.

3. In a hand stamp, a main frame having side members, a die platesupported in said frame between said side members and having partsprojecting therefrom by which the die plate is turned, and bushingscarried by said projecting parts having flanges located between saidprojecting parts and the side members of the frame and preventing i saidparts from contacting.

In testimony whereof I aiiiX my signature i in presence of twowitnesses.
